Specifications: Material: Metal, plastics, ceramics Voltage: AC 250V Current: 16A Temperature Range: 50°C - 300°C / 50°C - 400°C Product Life: > 100,000 cycles Electric Strength: AC 2000V / 1 min Normal Insulation Resistance: 100MΩ Contact Resistance: 50mΩ Wet Insulation Resistance: 10MΩ Temperature Response Rate: 1.0°C / min Minimum Current: 200mA Rod Diameter: 5mm / 6mm Rod Length: 54mm / 35mm Cable Length: 70cm Principle of Performance: When the temperature of the controlled object changes, the working fluid inside the thermostat responds with thermal expansion or contraction. This physical change in volume acts on a temperature-sensing bellows, causing it to expand or contract. Through a mechanical lever system, this movement drives the switch to open or close, achieving constant temperature control. Suitable for: Household appliances (showers, drum-type washing machines, heaters) Electric equipment (stainless steel automatic water boilers, electric frying pans, food machinery, medical equipment) Refrigeration industry (kitchen freezers, fresh cabinets, refrigerators, ice machines, fish ponds, cold drink machines, heating machines) requiring temperature control Package Includes: 1 set of mechanical thermostat
